The shell is similar to the anti-static steel access floor panel. But the inside of the shell is empty without cement. The bottom and top steel plate is perforated or some type of bottom will reinforced by rids. The perforated access floor panel is used the areas that need ventilation. It will be often used together with the steel anti-static access floor. The perforated rate will be from 17% to 50% according to the requirements of the application. The covering will be HPL, PVC or ceramic tile. Steel perforated panels is also called Air Flow panel because of many holes drilled through them. Perforated panels are of accurate size and thickness, interchangeable with steel access floor panels, wood core panels or calcium sulphate panels. Specially designed and well manufactured damper is also available for perforated panels.


  1. Made of steel plate, high mechanical strength, high loading capacity, good fire resistance.
  2. Interchangeable with wood core panel/calcium sulphate panel
  3. Provide superior cooling for managing heat loads in mission critical facilities

4, The ventilation rate will be 17%~45% and can satisfy different requirements of cleaning room.


Application area

Steel anti-static perforated access floor is often used in the cleaning factory of semi conductor, micro electrical chip, integrated circuit, communicated equipment, or areas that need ventilation for underfloor air conditioning system.
